I’ve been using Excel for data cleaning until I discovered how powerful pandas are for data analysis and data cleaning. In this article I want to go over basics of how to use pandas for cleaning data in excel files.

Fisher’s Linear Discriminant Analysis (LDA) is a dimension reduction technique that can be used for classification as well. In this blog post, we will learn more about Fisher’s LDA and implement it from scratch in Python.

This post is a deep-dive into programmatically trading on the Ethereum / Bancor exchange and exploiting a game-theoretic security flaw in Bancor, a high-profile smart contract on the Ethereum blockchain.

In Python, a class can inherit features and attributes from multiple classes and thus, implements multiple inheritance. MRO or Method Resolution Order is the hierarchy in which base classes are searched when looking for a method in the parent class.

Imagine that you are developing a machine learning model to classify articles. You have managed to get an unreasonably large text file which contains millions of identifiers of similar articles that belong to the same class. You are unsure whether identifiers that are close to each other are independent.

Medium has a large amount of content, a large number of users, and an almost overwhelming number of posts. When you try to find interesting users to interact with, you’re flooded with visual noise. I define an interesting user as someone who is from your network, who is active, and who writes responses that are generally appreciated by the Medium community.

Clustering is a type of Unsupervised learning. This is very often used when you don’t have labeled data. K-Means Clustering is one of the popular clustering algorithm. The goal of this algorithm is to find groups(clusters) in the given data. In this post we will implement K-Means algorithm using Python from scratch.

mailproxy is a simple SMTP proxy. It receives emails through an unencrypted, unauthenticated SMTP interface and retransmits them through a remote SMTP server that requires modern features such as encryption and/or authentication. mailproxy is primarily useful for enabling email functionality in legacy software that only supports plain SMTP.
